Birds of Britain 



males in their first winter have a black bill. Total length 

 lO'l in. ; wing 5 in. 



The female is of a uniform dull sooty brown above ; 

 chin greyish, with dark brown streaks ; chest reddish 

 brown, each feather with a darker tip, giving it a mottled 

 appearance. Flanks dark brown, sometimes mottled with 

 lighter. Vent sooty grey. 



The young of both sexes resemble the female in 

 general appearance, but the feathers of the head and back 

 have light shafts. Young males are a shade darker in 

 colour. Generally distributed throughout the British Isles, 

 except Shetland and the Outer Hebrides, where it only 

 occurs on migration. 



THE DUSKY THRUSH 



Turdus dubius, Bechstein 



This species breeds in Eastern Siberia, from the valley 

 of the Yenesei to the Pacific. Several stragglers have been 

 obtained at different times in Europe, but the only British 

 example was shot in 1905 near Gunthorpe, Notts. 



The general colour is greyish brown above, streaked 

 with darker, becoming more rufous on the rump. Quills 

 broadly margined with rufous. Below white, breast and 

 flanks boldly marked with black ; under wing coverts and 

 axillaries rufous.
